### 10.3.2.6 Minimizing Disruption

Changing the configuration of a router SHOULD have minimal affect on the network. Routing tables SHOULD NOT be unnecessarily flushed when a simple change is made to the router. If a router is running several routing protocols, stopping one routing protocol SHOULD NOT disrupt other routing protocols, except in the case where one network is learned by more than one routing protocol.

DISCUSSION

  It is the goal of a network manager to run a network so that users of the network get the best connectivity possible. Reloading a router for simple configuration changes can cause disruptions in routing and ultimately cause disruptions to the network and its users. If routing tables are unnecessarily flushed, for instance, the default route will be lost as well as specific routes to sites within the network. This sort of disruption will cause significant downtime for the users. It is the purpose of this section to point out that whenever possible, these disruptions should be avoided.
